Step 5. Check the wiring harness between C-217 
ETACS-ECU connector terminal No.3 and body 
earth.

NOTE: 

Prior to the wiring harness inspection, check junction 
block connector C-205, and repair if necessary.

•

Check the earth wires for open circuit.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

−

 How to 

Cope with Intermittent Malfunction 

P.00-6

).

NO : 

Repair the wiring harness.

Step 6. Retest the system.

Check that the battery power supply circuit to the 
ETACS-ECU is normal.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

−

 How to 

Cope with Intermittent Malfunction 

P.00-6

).

NO : 

Replace the ETACS-ECU.

TONE ALARM

INSPECTION PROCEDURE B-1: Lamp reminder buzzer function does not work normally.

CAUTION

Whenever the ECU is replaced, ensure that the 
input and output signal circuits are normal.

COMMENTS ON TROUBLE SYMPTOM
The ETACS-ECU operates this function in 
accordance with the input signals below.

•

Ignition switch (IG1)

•

Driver's door switch

•

Tail lamp switch

•

Headlamp switch

If this function does not work normally, these input 
signal circuit(s) or the ETACS-ECU may be 
defective.

POSSIBLE CAUSES

•

Malfunction of the driver's door switch

•

Malfunction of the column switch

•

Malfunction of the ETACS-ECU

•

Damaged harness wires and connectors

DIAGNOSTIC PROCEDURE

Step 1. Check the power supply circuit.

When the ignition switch is turned to the LOCK 
(OFF) position, check if the hazard warning lamps 
illuminate.

Q: Is the check result normal?

YES : 

Go to Step 2.

NO : 

Refer to inspection procedure A-2 "Check 
the ETACS-ECU battery power supply 
circuit 

P.54B-52

."

Step 2. Pulse check

Check the input signals below, which are related to 
the lamp reminder buzzer function.

OK: The MUT-II/III sounds or the voltmeter 
needle fluctuates.

Q: Is the check result normal?

All the signals are received normally. : 

Go to Step 

3.

The ignition switch (IG1) signal is not received. : 

Refer to inspection procedure N-2 "The 
ignition switch (IG1) signal is not received 

P.54B-301

."

The driver's door switch signal is not received. : 

Refer to inspection procedure N-4 "The front 
door switch signal is not received 

P.54B-315

 <L. H. drive vehicles> or 

P.54B-317

 <R. H. drive vehicles>."

The tail lamp switch signal is not received. : 

Refer 

to inspection procedure N-5 "The column 
switch (lighting and turn-signal lamp switch) 
signal is not received 

P.54B-319

."

The headlamp switch signal is not received. : 

Refer to inspection procedure N-5 "The 
column switch (lighting and turn-signal lamp 
switch) signal is not received 

P.54B-319

."

Step 3. Retest the system.

The lamp reminder buzzer function should work 
normally.

Q: Is the check result normal?

YES : 

The trouble can be an intermittent 

malfunction (Refer to GROUP 00 

−

 How to 

Cope with Intermittent Malfunction 

P.00-6

).

NO : 

Replace the ETACS-ECU.
